"I See the Light" is a song written by composer Alan Menken and lyricist Glenn Slater for Walt Disney Animation Studios' 50th animated feature film Tangled (2010). A duet originally recorded by American recording artist and actress Mandy Moore and American actor Zachary Levi in their respective film roles as main characters Rapunzel and Flynn Rider, the folk-inspired pop ballad serves as both the film's love and theme song. Lyrically, "I See the Light" describes the developing romantic relationship between Rapunzel and Flynn, and is featured as the seventh track on the film's soundtrack album.
